Our Technology

APJeT®’s plasma systems operate at atmospheric pressure, room temperature, and industrial line speeds using inexpensive gases. Our plasma systems are carefully engineered to cause powerful chemical surface reactions without altering the bulk strength and other desirable properties of the substrate.

APJeT® is an expert at engineering plasma and optimizing chemical reactions. These chemical reactions can be divided into two primary categories: Plasma Activation and Plasma Coating. Plasma Activation involves a direct reaction between the plasma and the substrate.
Plasma Coatings involve a reaction between the plasma, the substrate, and the chemical finish.

What is Plasma?

Plasma is considered the fourth state of matter. It occurs when enough energy is added to gas molecules to liberate one or more of electrons from their electron cloud.

Plasma Activation

Plasma Activation involves a direct reaction between the plasma and a substrate. APJeT® is an expert at engineering plasma to deliver the desired surface functionality. This can be achieved by changing plasma parameters such as power, duration, and gas composition. The combination of these allows us to create new chemical moieties on the surface of substrates.

Common chemical moieties include oxygen and nitrogen functional groups.

Oxygen functional groups increase the surface energy of a substrate and improve wetting.

Molecules are composed of three parts, positively charged protons, negatively charged electrons, and neutral neutrons. Under normal conditions, the number of protons equals the number of electrons resulting in a net charge of zero. The molecule as a whole is considered quasi-neutral.

However, when the negatively charged electron escapes the electron cloud, the remaining molecule now has a positive charge.

The existence of positive and negative charges results in a plasma. Unlike a gas, the plasma is charged and can be affected by magnetic and electrical forces.

Plasma Activation involves a direct reaction between the plasma and the substrate. Plasma Coatings involve a reaction between the plasma, the substrate, and the chemical finish to create a coating on the surface of the substrate.

Plasma Activated Hydrophilicity

APJeT® plasma systems can be used to increase the surface tension of a substrate, making it hydrophilic or water-loving. When a substrate is introduced to a hydrophilic APJeT® plasma, oxygen functional groups are generated on the surface of the substrate. These groups increase polarity, causing water to be more easily absorbed.

These hydrophilic polar groups can improve dyeability and printability, reduce contact angle, increase wettability and promote superior adhesion.

Improved surface polarity can be beneficial to many applications.

Plasma Coating & Finishing

Plasma Coatings involve a reaction between the plasma, the substrate, and an a chemical to create a coating or finish on the surface of the substrate. Each finish is achieved with a proprietary blend of chemistry tailored to achieve the desired performance on the substrate.

First, the chemistry is applied to the surface of the substrate using a chemical applicator, such as a sprayer or digital printer (DriStream). No wastewater is produced during this chemical application process.

Next the substrate enters the plasma region where the chemistry is cured to the substrate without any heat or elevated temperatures.

Due to the elimination of heat and water, the APJeT® process provides both a cost savings and environmental benefit.

APJeT®’s proprietary chemical coatings include several functional finishes including the following: durable water repellent, anti-microbial, wicking, and silicone release.

DriStream

APJeT®’s unique patent-pending DriStream technology allows us to print and cure our proprietary chemical formulations into patterns of varying concentration or shape. By printing alternating areas of hydrophilic and hydrophobic chemistry, we are able to control fluid-flow mechanics and direct moisture from one area to another.

One exciting application of this DriSTream technology is sweat channeling.

DriStream technology can also be used for other applications like personal hygiene and health care to control moisture content and fluid flow. DriStream also has unique aesthetic applications like in Emerge Swimwear.
